And the porter carrying it will be conspicuous (5,3)
I believe the answer is:
stand out
'be conspicuous' is the definition.
(I've seen this before)
'and the porter carrying' is the wordplay.
'the porter' becomes 'stout' (porter can mean stout).
'carrying' is an insertion indicator.
'and' put inside 'stout' is 'STAND OUT'.
'it will' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for stand out that I've seen before include "Protrude" , "Don't agree to - project" , "Catch the eye" , "Be proud" , "Distinguish oneself" .)
